SHEET OPERATING AND DISPLAY MECHANISM.

Application filed March 19, 1912.

T 0 all whom it may concern Be it known that I, EARL W. LANFORD, a citizen of the United States, residing at Spartanburg, in the county of Spartanburg and State of South Carolina, have invented new and useful Improvements in Sheet Operating and Display Mechanisms, of which the following is a specification.

This invention is an improved sheet operating and display mechanism designed for use especially in an order book cabinet arranged for use by salesmen in wholesale groceries and other business and consists in the construction, combination and arrangement of devices hereinafter described and claimed.

The accompanying drawing is a plan of a sheet operating mechanism constructed in accordance with my invention, a portion of the device being shown in horizontal section and the file holder being indicated as in open, extended position.

My improved sheet operating and display mechanism is here shown as 1n connection with an order book cabinet indicated at 1 and which may be used by salesmen in wholesale groceries and other business for holding an order book, a stock sheet and a discount roll, my mechanism being used for operating the stock sheet and the discount roll. The cabinet is represented as rectangular in form and is provided on one end with a casing 2 which extends transversely across the same and is divided by vertical walls 34 into chambers 5, 6 and 7. The upper side of the casing may be covered in practice by a glass plate. The top 9 of the order book cabinet is spaced from the bottom and is connected thereto at one side by a vertical wall which is not here shown, a chamber being thereby formed between the bottom and the cabinet top 9, which chamber is open at the remaining two sides 1218.

The cabinet has a file holder 14: pivotally mounted at one side as at 17 and arranged to be swung into the chamber formed by the cabinet or extended outwardly therefrom, this file holder having a vertical wall or flange 16 to close against the open side of the intake and being also provided with pins 18 or other suitable devices for holding data thereon. I also show a holding strip 39 on the upper side of the cabinet, the ends of which are attached to the top thereof.

A pair of rollers 19 and 20 which are arranged parallel With each other are mounted Specification of Letters Patent.

in the chamber 5, their spindles or axles having their bearings in the wall 8 and also in the outer wall 21 of said chamber. On the end of the spindle of the roller 19 which projects into the chamber 6 is a, friction gear 22 and on the corresponding spindle of the roller 20 which is longer than the spindle of the roller 19 is a friction gear 23, said friction gear being out of line with the gear 22. A pair of friction rollers 24: are also arranged in the chamber 5 and are mounted at the sides thereof. A printed or written stock list is engaged with and stretched between the friction rollers 2-1 and arranged to pass under the glass cover 8, the ends of the said stock list being connected to and partly rolled on the rollers 1920.

A pair of rollers 2627 are mounted in the compartment 7, their axles or spindles having their bearings in the partition wall 4: and also in the end wall 28. The axle of the roller 26 which projects into the compartment 6 has a friction gear 29 and the corresponding axle of the roller 27 has a friction gear 30 which is out of line with the gear 29, the axle or roller 27 being shorter than that of the roller 26. In the ends of the compartment 7 are friction rollers 31. In practice, a discount strip, is engaged with the friction rollers 31, stretched under the glass cover 8 and its ends are attached to and partly wound on the rollers 2627.

A tubular operating shaft 33 is mounted in bearings in the partition t and wall 28 for rotation and also for longitudinal movement and is provided at its inner end with a lever or other suitable friction gear 3 1 which may be engaged with either the gear 29 or the gear 30, to cause the rollers 26 27 to be turned in either direction required to move the discount strip in the required clirection. This tubular operating shaft has a milled operating disk or button 35 at its outer end. An operating shaft 86 is mounted for rotation and also for longitudinal movement in the tubular shaft and has at its inner end a rubber or other suitable friction wheel 37 which may be engaged with either the gear 22 or the gear 23 and turned so as to rotate the rollers 1920 as may be required to cause said rollers to move the stock rollers in the required direction. Atthe outer end of the said shaft 36 is a milled operating disk or button 38.

It will be understood that my improved cabinet provides convenient and easily-operated means for holding the order book, the file memoranda, such as price lists and the like and also the stock roll or strip and discount roll or strip and enables the stock roll and discount strips to be operated in either direction so as to display any desired parts thereof.

While I have herein shown and described a preferred form of my invention, I would have it understood that changes may be made in the form, construction and proportion of the several parts without departing from the spirit of my invention and within the scope of the appended claim.

I claim In a device of the class described the combination of tWo pairs of strip or sheet operating and display rollers, arranged with one roller of each pair in line with one roller of the other pair, said pairs of rollers being spaced apart, end for end, and said rollers being provided at their opposing ends with gears, the gears of the rollers of each pair being out of line with each other, a tubular operating shaft mounted for rotation and also for longitudinal movement and having a gear which may be engaged with either of the gears of one pair of rollers, and an operating shaft mounted for rotation and longitudinal movement in the tubular shaft and having a gear which may be engaged with either of the gears of'the other pairs of rollers.

In testimony whereof I afliX my signature in presence of two witnesses.

EARL W. LANFORD. Witnesses E. J. PETTIS, J. L. SHOCKLEY.
